Packaged capacitor component with multiple self-resonance frequencies

摘要

A packaged capacitor component such as a surface mount technology capacitor component may be formed with multiple self-resonant frequencies. The capacitor component may include multiple capacitor portions separated by dielectric layers. The capacitor portions may each be formed from interleaving conductive layers. Additional dielectric layers may be interposed between the interleaving conductive layers. Each capacitor portion may be characterized by a corresponding self-resonance frequency. If desired, a packaged capacitor component having multiple self-resonant frequencies may be formed by stacking multiple surface-mount capacitor components. Each of the stacked surface-mount capacitor components may include interleaving conductive layers that are centered between top and bottom surfaces of that component. Packaged capacitor components having multiple self-resonance frequencies may be used as direct-current blocking capacitors or decoupling capacitors.
